6.2 V Zener — the voltage reference in the order code
The HZM6.2NB3TL-E is a Zener diode from Rohm, with the 6.2 in its order code indicating a nominal zener voltage of 6.2 V. This is the primary parameter for circuit fit — it sets the regulation point in shunt voltage references, clamping rails, or protection circuits.
It is also ROHS3 Compliant, clearing the regulatory gate for EU and global markets without exemption concerns.
